Quick read
Key points
- 1
Psychosis is a symptom, not a single condition, involving a loss of some contact with shared reality — this can include hearing, seeing, or believing things that others don't experience or share (hallucinations and delusions), along with confused or disorganised thinking. It can occur as part of several conditions, including schizophrenia, bipolar disorder, severe depression, or sometimes due to substance use, extreme stress, sleep deprivation, or a physical illness.

What is Psychosis?
Psychosis is a symptom, not a single condition, involving a loss of some contact with shared reality — this can include hearing, seeing, or believing things that others don't experience or share (hallucinations and delusions), along with confused or disorganised thinking. It can occur as part of several conditions, including schizophrenia, bipolar disorder, severe depression, or sometimes due to substance use, extreme stress, sleep deprivation, or a physical illness.
Psychosis is treatable, and most people who receive early, appropriate care see significant improvement. Early intervention services specifically for first-episode psychosis have been shown to lead to better long-term outcomes.

Clinical context
Early treatment leads to better outcomes
Getting assessment and treatment as early as possible after psychosis symptoms begin is strongly linked with better long-term recovery, which is why early intervention psychosis services exist specifically for this purpose.

Practical steps
This Requires Professional Assessment and Treatment
Psychosis needs prompt professional evaluation — with the right support, most people recover well, particularly when treatment begins early.
- 1Seek assessment promptly.A GP or mental health service can arrange urgent evaluation, including referral to early intervention psychosis services where available.
- 2Stay calm and non-confrontational if supporting someone.Gently expressing concern and encouraging professional help tends to be more effective than arguing about what is or isn't real.
- 3Maintain a stable, low-stress environment.Reducing stress and maintaining regular routines can support recovery alongside treatment.
- 4Engage with the recommended treatment plan.This often includes medication and therapy, both of which have good evidence for helping manage and reduce psychosis symptoms.
- 5Build a support network.Family involvement and peer support, where appropriate, often support better long-term outcomes.
